Improving case study research in medical education: A systematised review

Context:Case study research (CSR) is a research approach that guides holistic investigation of a real phenomenon. This approach may be useful in medical education to provide critical analyses of teaching and learning, and to reveal the underlying elements of leadership and innovation. There are variations in the definition, design and choice of methods, which may diminish the value of CSR as a form of inquiry.Objectives:This paper reports an analysis of CSR papers in the medical education literature. The review aims to describe how CSR has been used and how more consistency might be achieved to promote understanding and value.Methods:A systematised review was undertaken to quantify the number of CSR articles published in scholarly medical education journals over the last 10 years. A typology of CSR proposed by Thomas and Myers to integrate the various ways in which CSR is constructed was applied.Results:Of the 362 full‐text articles assessed, 290 were excluded as they did not meet the eligibility criteria; 76 of these were titled ‘case study’. Of the 72 included articles, 50 used single‐case and 22 multi‐case design; 46 connected with theory and 26 were atheoretical. In some articles it was unclear what the subject was or how the subject was being analysed.Conclusions:In this study, more articles titled ‘case study’ failed than succeeded in meeting the eligibility criteria. Well‐structured, clearly written CSR in medical education has the potential to increase understanding of more complex situations, but this review shows there is considerable variation in how it is conducted, which potentially limits its utility and translation into education practice. Case study research might be of more value in medical education if researchers were to follow more consistently principles of design, and harness rich observation with connection of ideas and knowledge to engage the reader in what is most interesting

Artificial consciousness and the consciousness-attention dissociation

Artificial Intelligence is at a turning point, with a substantial increase in projects aiming to implement sophisticated forms of human intelligence in machines. This research attempts to model specific forms of intelligence through brute-force search heuristics and also reproduce features of human perception and cognition, including emotions. Such goals have implications for artificial consciousness, with some arguing that it will be achievable once we overcome short-term engineering challenges. We believe, however, that phenomenal consciousness cannot be implemented in machines. This becomes clear when considering emotions and examining the dissociation between consciousness and attention in humans. While we may be able to program ethical behavior based on rules and machine learning, we will never be able to reproduce emotions or empathy by programming such control systems—these will be merely simulations. Arguments in favor of this claim include considerations about evolution, the neuropsychological aspects of emotions, and the dissociation between attention and consciousness found in humans. Ultimately, we are far from achieving artificial consciousness

Multi-agent simulations for emergency situations in an airport scenario

This paper presents a multi-agent framework using Net- Logo to simulate humanand collective behaviors during emergency evacuations. Emergency situationappears when an unexpected event occurs. In indoor emergency situation, evacuation plans defined by facility manager explain procedure and safety ways tofollow in an emergency situation. A critical and public scenario is an airportwhere there is an everyday transit of thousands of people. In this scenario theimportance is related with incidents statistics regarding overcrowding andcrushing in public buildings. Simulation has the objective of evaluating buildinglayouts considering several possible configurations. Agents could be based onreactive behavior like avoid danger or follow other agent, or in deliberative behaviorbased on BDI model. This tool provides decision support in a real emergencyscenario like an airport, analyzing alternative solutions to the evacuationprocess.Publicad

Evaluation of a novel digital environment for learning medical parasitology.

open access articleEukaryotic parasites represent a serious human health threat requiring health professionals with parasitology skills to counteract this threat. However, recent surveys highlight an erosion of teaching of parasitology in medical and veterinary schools, despite reports of increasing instances of food and water borne parasitic infections. To address this we developed a web-based resource, DMU e-Parasitology®, to facilitate the teaching and learning of parasitology, comprising four sections: theoretical; virtual laboratory; virtual microscopy; virtual clinical case studies. Testing the package was performed using a questionnaire given to ninety-five Pharmacy students in 2017/18 to assess effectiveness of the package as a teaching and learning tool. 89.5% of students reported appropriate acquisition of knowledge of the pathology, prevention and treatment of some parasitic diseases. 82.1% also welcomed the clinical specialism of the package as it helped them to acquire basic diagnostic skills, through learning infective features/morphology of the parasites

Improving the validity of Script Concordance Testing by optimising and balancing items

Background: A script concordance test (SCT) is a modality for assessing clinical reasoning. Concerns had been raised about the plausible validity threat to SCT scores if students deliberately avoided the extreme answer options to obtain higher scores. The aims of the study were firstly to investigate whether students’ avoidance of the extreme answer options could result in higher scores, and secondly to determine whether a ‘balanced approach’ by careful construction of SCT items (to include extreme as well as median options as model responses) would improve the validity of an SCT. Methods: Using the paired sample t-test, the actual average student scores for 10 SCT papers from 2012–2016 were compared with simulated scores. The latter were generated by recoding all ‘2’ responses to ‘1’ and ‘+2’ responses to ‘+1’ for the whole and bottom 10% of the cohort (simulation 1), and scoring as if all students had chosen ‘0’ for their responses (simulation 2). The actual average and simulated average scores in 2012 (before the ‘balanced approach’) were compared with those from 2013–2016, when papers had a good balance of modal responses from the expert reference panel. Results: In 2012, a score increase was seen in simulation 1 in the third-year cohort, from 50.2 to 55.6% (t [10] = 4.818; p = 0.001). Since 2013, with the ‘balanced approach’, the actual SCT scores (57.4%) were significantly higher than scores in both simulation 1 and simulation 2 (46.7% and 23.9% respectively). Conclusions: When constructing SCT examinations, apart from the rigorous pre-examination optimisation, it is desirable to achieve a balance between items that attract extreme responses and those that attract median response options. This could mitigate the validity threat to SCT scores, especially for the low-performing students who have previously been shown to only select median responses and avoid the extreme responses

The benefits of prototypes: The case of medical concepts

In the present paper, we shall discuss the notion of prototype and show its benefits. First, we shall argue that the prototypes of common-sense concepts are necessary for making prompt and reliable categorisations and inferences. However, the features constituting the prototype of a particular concept are neither necessary nor sufficient conditions for determining category membership; in this sense, the prototype might lead to conclusions regarded as wrong from a theoretical perspective. That being said, the prototype remains essential to handling most ordinary situations and helps us to perform important cognitive tasks. To exemplify this point, we shall focus on disease concepts. Our analysis concludes that the prototypical conception of disease is needed to make important inferences from a practical and clinical point of view. Moreover, it can still be compatible with a classical definition of disease, given in terms of necessary and sufficient conditions. In the first section, we shall compare the notion of stereotype, as it has been introduced in philosophy of language by Hilary Putnam, with the notion of prototype, as it has been developed in the cognitive sciences. In the second section, we shall discuss the general role of prototypical information in cognition and stress its centrality. In the third section, we shall apply our previous discussion to the specific case of medical concepts, before briefly summarising our conclusions in section four

Theorising and practitioners in HRD: the role of abductive reasoning

Purpose – The purpose of this paper is to argue that abductive reasoning is a typical but usually unrecognised process used by HRD scholars and practitioners alike. Design/methodology/approach – This is a conceptual paper that explores recent criticism of traditional views of theory-building, based on the privileging of scientific theorising, which has led to a relevance gap between scholars and practitioners. The work of Charles Sanders Peirce and the varieties of an abductive reasoning process are considered. Findings – Abductive reasoning, which precedes induction and deduction, provide a potential connection with HRD practitioners who face difficult problems. Two types of abductive reasoning are explored – existential and analogic. Both offer possibilities for theorising with HRD practitioners. A range of methods for allowing abduction to become more evident with practitioners are presented. The authors consider how abduction can be used in engaged and participative research strategies. Research limitations/implications – While this is a conceptual paper, it does suggest implications for engagement and participation in theorising with HRD practitioners. Practical implications – Abductive reasoning adds to the repertoire of HRD scholars and practitioners. Originality/value – The paper elucidates the value of abductive reasoning and points to how it can become an integral element of theory building in HRD
